Question

Quadrilateral PQRS is reflected over the y-axis to create quadrilateral P'Q'R'S'. which angle has the greatest measure? (P =90° , Q=120° , R=100° , S=50°)



A. P'

B. Q'

C. R'

D. S'​

Answer 1

Answer:

B.Q'

Step-by-step explanation:

Quadrilateral PQRS is reflected over the y-axis to create quadrilateral P'Q'R'S'.

Angle P=90 degree

Angle Q=120 degree

Angle R=100 degree

Angle S=50 degree

We know that in reflection across y- axis the size of figure  does not change.

The coordinates of figure are change.

Therefore, angle measure of quadrilateral P'Q'R'S' are remains same as in quadrilateral PQRS.

The angle measure  of Q is largest.

Angle Q=Angle Q'

Hence, the angle which has greater measure=Q'
